UNITED STATES MARTIN KREMSER, OF INDIANAPOLIS, INDIANA.

IMPROVEMENT IN METAL-PLANING MACHINES.

Speciication forming part of Letters Patent No. 119,156, dated September 19, 1871.

To all rwhom 'it may concern:

Be it known that I, MARTIN KREMSER, of Indianapolis, Marion county,'and State of Indiana, have invented a new and useful Improvement in Iron-Planers, of which the following is a specification:

The nature of the invention consists in attaching an extra horizontal slide to the cheeks of the planer, which can be so arranged that the tool will be held at a considerable distance in front of the cheeks of the planer. The object of the invention is to plane work too Wide to pass between the cheeks of an ordinary planer.

Figure 'l is a top view of the device, showing how it is arranged between the cheeks of the planer 5 Fig. 2, a cross-section ofthe device Fig.

3, a sectional edge view of the device, showing a section of the planer-cheeks, the upright slide, and a section of the upright screw. Fig. 4, are cross-sections of the planer-cheek and the upright slide. Fig. 5 is a view of the principal parts of a planer with the device attached.

b c l e is a frame of cast metal. lThe sides b c and d e are planed with parallel slides which are fltted to gibs in the upright slides IL and 7c. These upright slides h and krun upon guides on the planer-cheeks f and g, and are actuated by the screw l. l The frame or slide b c d e is moved in its gibs by the screw o. This screw o is turned by the crank p. a is the cross-head of the planer,

and may be fastened to the end c d of the slide b c d e by means of bolts, or in any other convenient way. Upon this cross-head a is fastened the upright tool-slide, as represented in Fig. 5, all being so arranged that the tool can be pushed out to any desired distance in front of the cheeks of the planer by sliding forward the frame b c d e, which is actuated, asaforesaid, by turning the screw o. l

To use my said device the work is put upon the bed of the planer, as usual, and the crosshead moved out away from the cheeks, by means of the screw o and the slide b c d e, so far that anything too wide to pass the cheeks will go entirely past the tool without striking the cheeks, to which length the stroke of the planer may be regulated. Otherwise it is used as an ordinary planer.

I claim as my invention- In combination with the upright posts of a I Witnesses:
